A comprehensive range of single & double pulleys to cover every aspect of one & two man applications in rescue, access and arborist industries. ISC’s new Micro pulley’s are only used when a compliance productis required, for example as part of a prussic knot loop, for rope climbing but have ex-stock availability and are competitively priced.

The small & medium Eiger range offers a superb strength to weight ratio as 7000 grade aerospace aluminium is used throughout and can be used with a variety of rope diameters. Small Eiger pulleys are typically rated for one-man use where as medium Eigers are designed to accommodate two-man use or heavier materials loads. The Rp031 Double redirect is a relatively recent addition to the arborist range specifically designed without the centre plate to allow smooth running for double ropes. The medium Eiger range is compliant with NFPA requirements.

A range of heavy duty Aluminium pulleys for use in rescue, where weight & strength is vital. The prussik range is specifically designed for mountain rescue/industrial climbing wherever rope rescue systems are being utilised and is available in all aluminium, or all stainless steel.

The Rp700 family of rescue pulleys is the professionals choice. Light weight and super strong these have the durability for any rescue kit and can be rigged in 3:1 ratio to 5:1 ratio. The Rp700 incorporates one-way needle bearings which allow a high level of descent control when used in a hauling kit and are easily comparable with rollgliss or shorhoist. The Rp702 and 703 are single and double wheeled pulleys that incorporate a stainless steel locking cam which would automatically stop the rope in the event of loss of control. The Rp700 family has swinging cheeks specifically designed to accept even the largest karabiners.

ISC is further developing its range of single and tandem stainless pulleys for use on wire ropes to offer various sizes with fixed or moving bollards. These are most often used in rope slides, zip wires, arial rigging and rope courses and in some offshore drilling operations where the environment is severe.

Aluminium cast pulleys are used primarily in the arborist industry with heavy duty ropes as part of a rigging/lowering kit. A range of 3 pulleys can be used with a variety of rope diameters from 13mm -20mm offering working load limits of 2000kg - 4000kg incorporating a safety factor of at least 5:1. The cast pulley family is currently being redesigned to look more modern and to reduce their overall weight. A super strong (2000kg WLL) stainless steel screwblock pulley is also available.

As in all the equipment that is used to protect lives at work, strength and durability are key issues. That’s why we prefer to use oil impregnated sintered bronze (oilite) bushes across the range rather than bearings. The difference in use when new is marginal, but after the wear and tear associated with regular use the oilite bush remains robust and effective even under high loads. Pulleys with bearings are only effective as long as the seal remains in good working order. As soon as there is an ingress of dirt, debris or even water they can quickly deteriorate leaving the pulley practically unusable. Ongoing care and maintenance is key to the operational safety of any product.

All ISC pulleys are batch tested and 100% inspected. Full traceability is required as part of our ISO9001 Quality system. In line with our new branding policy standard ISC pulleys will in future be red (colour options are available).
